Smidl disks e are provided -with a hole in the centre'to receive the spindle A.

i The spokes a are-made of the ordinary materials and shape-except where they lenter between the 'RangesI A anda. They aie'not provided with u. teuon, hut are Atapered so as to ft against each other, and project beyond the huh in the ordinal-'y way, so as to occupy all the space between the flanges A( and a.

The operation is such that by removing the mit 'wond the flange A', and placing one of the disks e against the face of the ilenge a2, and placing the spckcs'a; so formed as above dcsctihefl, against the sarl disk, and piacingthe other of' said disks e against the spokes a on the opposite side of the same, andv putting the flange A', with its faceside to saiil'disk, :incl turning on the nut'. n, the innge A is/forced against saidjdsk, and Said" diskse aud spokes a are forced against the frime of the flange a?, whereby said spokes a are firmly held in posi.' tion Between the said flanges A and a2, as shown. A ring oikey mcy be cast upon or seem-eclats the faces of the flanges A' and a2, or either of them, which engages with a mortisc in the spokes a, to hold said spokes a more rmly in position, if required. Y

Constructed a-s above described, it constitutes a. cheap, neat, ond convenient hub and axle-box combined,

. 'the advantages of which are that the elastic disks e are mede to conform to any unequal surfaces on the spokes for the purpose specified.

a, und any injuiyto said spokes froml the jaring of the' carriage is prevented, and that no additional vbox is ngquired, andtliat 'a spoke or spokes may at any time he taken out and renewed without cutting the tire. We claim as new, and desire to secure by Letters Pn.tent- The coller .LX/,provided with a. series of pins upon itssiace, entering through 'the elastic disk c, and with' the tenons formed in the spokes, when said collar is adapted to slide upon the spindle A, as herein described, f
